An integrated software tool environment is presented, and amethodology is proposed for the operational support of the localauthority, for analysis of the impact of transport measures in termsof network energy consumption and pollutant emissions. It is based onwork done by the European Union within the save program (specificactions for vigorous energy efficiency)-Slam project (supportinglocal authorities methodology). As background, the Slam project isdescribed, with the principal aspects and needs of environmental andtraffic network management. The central section defines a methodologyable to support technicians in recognizing the traffic asset anddecision makers in evaluating interventions on urban transportinfrastructures or technological systems. The role of the differentmodels and their interactions with the transport telematics servicescurrently active on the Florence (Italy) network is discussed.Finally, the procedure for calculating the traffic impacts on energyconsumption is described with the help of a test case, the evaluationof a dedicated bus corridor in Florence.
